Hi! Just noticed an issue I'm experiencing with fly-out spells like Summon Demon, Poisons, or Greater Blessings.

I have a 3x3 bar (9 buttons, 3 columns) that's shoving the fly-out arrow and its popup bar in the wrong direction. I'm able to fix it temporarily by setting the column size to a regular button size of 12, which I guess tells the game the bar should be facing "this" way instead of "that" way but this fix resets when logging out. I've made sure it's a Dominos issue by having Dominos as the only addon enabled on this character while testing it.

The button in question is at the top middle of the bar so it should be opening the flyout menu upward but it's instead opening to the side, into another button (that's usually occupied!)

Here's a screenshot of that bar, for reference.
